Which refrigerant is considered high or very high pressure refrigerant?

Would a se-leave pressure of 1040 mb be considered high or low pressure?

Yes, 1040mb is a very high surface pressure.

What kind of head pressure would you experience if the condenser fan motor became inoperative?

If the condenser fan motor became inoperative, the head pressure in the refrigeration system would increase significantly. This is because the condenser fan motor is responsible for dissipating heat from the refrigerant, and without it, the heat cannot be effectively removed. As a result, the refrigerant would not be able to condense properly, leading to higher pressure in the system. This increase in head pressure can cause damage to the compressor and other components in the system if not addressed promptly.

You have a subaru legacy 1991 the ac stopped working the compressor is engaging on and of constantly did put cooling in it but still dus not work Have anybody any idea where to look for the problem?

If you added refrigerant, was the compressor running better before or after you added refrigerant? Compressor cycling on-off can be caused by defective low pressure switch (very rare on Subarus), or low on refrigerant. Best to test with a good refrigerant gauge-- resting pressure (system off) should be between 45 and 80 psi (higher pressure with higher temperature) on the suction side. Make CERTAIN you attach the gauge to the suction side (the side with the larger diameter hose). When the compressor cycles on, if suction pressure drops below approx 23-29 psi, the low pressure switch will shut off compressor to prevent damage. If low suction pressure, cure is to add refrigerant, little at a time. NOTE: Refrigerant is under high pressure, and is very dangerous. If you are not trained to handle refrigerant, suggest take this problem to a shop to check out.

How do you refill the AC refrigerant on a blazer 1995?

You only add refrigerant thru the LOW pressure valve. First check the pressure with a pressure gauge (should read between 25-45 psi) If low then start engin and turn AC on high. Attach refrigerant canaster to the low pressure valve to release refrigernt into the system. Canaster turns very cold and condensation appers on it as it releases into you a/c. Recheck pressure to make sure that is is at the proper PSI. You will hear the compressor kick on and off and the gague will fluctuate between the proper range.

When is the most heat removed from refrigerant in the condensing process?

When the temperature of the air passing over the condenser is very low. Ex: Home A/c with out condenser, More heat can be removed if the out door ambient is 60f compared to 90f. Efficiency also increases with this.

How does an air conditioning system work?

An air conditioning system works in a cycle. One side of the system is considered the high pressure side and the other side is considered the low pressure side. The air condition compressor can be viewed as the center line between these "sides" of the system. Refrigerant R-12 or R-134a (the most common types of refrigerant used in mobile A/C systems) remains at rest in the components an lines of the system until you turn on your A/C. At that point the electromagnetic clutch on the compressor engages and draws refrigerant (in a gas/liquid form) into it to be pumped throughout the system. Upon leaving the compressor the refrigerant has been compressed and thereby heated up resulting in it being transformed into a gaseous state. The refrigerant then travels into the condenser which removes heat from the refrigerant in an effort to return it to a liquid form. From the condenser the refrigerant will often pass through an expansion valve or an orifice (the other component in the system which divides the high an low pressure "sides") where it it "metered" to change it from High pressure on the compressor outlet side to low pressure. After the expansion valve the refrigerant moves into the evaporator. The evaporator is the component that actually removes heat from the air being forced through it by your vehicle's blower fan which pushes "cooled" or "conditioned" air through your vents. From the evaporator, the refrigerant (now mostly in gas form again) travels through a reciever-drier with removes moisture caused by condensation (which may have resulted from the heating and cooling of the refrigerant) before it returns once again to the compressor to repeat the cycle.*Note:R-12 and R-134A have very low boiling points and can be utilized in a liquid for due to the internal pressure of the A/C system.R-12 is no longer produced to the CFCs and their environmental impact.The A/C compressor's electromagnetic clutch is also engaged when using a "defrost" function in most vehicles.There are high and low pressure sides of the system, the condenser is on the high side and the evaporator is on the low side.Components include:CompressorCondenserExpansion valve/ orificeEvaporator/ blower motorReciever-drier

Is it possible to have a very high systolic pressure and a very low diastolic pressure?

No.

What is considered high pressure in a fluid line. ie at which pressure would a pipe containing a fluid transfer from beig low pressure to high pressure?

The term high pressure is extremely vague - as is low pressure. The answer to the question of pressure classification is based on what fluid and the type of handling equipment. Commericial and industrial hydraulics traditionally recognize pressures of 3,000 PSI and under. So when discussing hydraulic oil systems high pressure is anything above 3,000 PSI. In consumer pressure washers anything above 2,000 PSI would be considered high pressure. In industrial triplex pump applications, 2000 PSI would be considered very low pressure. Gases are also considered fluids, and gases have completely differrent pressure classifications. In summary, when asking about a pressure classification one must include the additional information - namely the fluid and the application.

High pressure gases?

when the collision between the gas molecules and the container in which the gas exist is very high.....then the pressure of the gas is very high

Can nitrogen be compressed?

Yes, nitrogen can be compressed under high pressure. When compressed, nitrogen gas can be stored in cylinders or tanks for various industrial applications such as in manufacturing processes or for use as a refrigerant.

Bp 164 114 is it danger?

A blood pressure of 164/114 is quite high. It is not possible to say whether it is dangerous since everybody is different. If you go to the doctor and have this blood pressure, you will likely be started on a blood pressure medication because it is considered very high.

Is an area with very little rainfall like to be a high or low pressure center?

high pressure most likely
